Paying the monthly subscription makes sense to me only during our Annual Mudspike Flights 
The rest of the year I would rather want to own my copy of the software and play irregularly as I want.
On the other hand it can be no selling price, no monthly subscription. They can just charge the airport and airspace usage fees 
Fuel & “environmental” surcharges? 
@Wes’s comment was meant in jest but…given the EU’s policies on the environment and global warming, I wonder if we could get some EU legislation passed that would give us flight simmers subsidies for sim flying the Mudspike Annual flights rather than really flying them! i.e. by not actually flying several thousand miles in an actual aircraft–with those big spinning CO2 footprint engines running the whole way–we are significantly reducing the greenhouse gases released into the environment!
The first step for me is to get Hampton, VA admitted to the EU…
…sometimes just have these great thoughts and just have to share. 
You would probably have to prove your electricity supply is generated sustainably, or that you had a plan to plant as many trees as necessary to offset the carbon released in powering your sim 
Of course we planted trees! We all turned the tree generation slider to 100%.
You should also move the bird strike slider to 0 to keep the virtual bird deaths down.
I’ll put a sign up outside the village I live in saying it’s twinned with Hampton V. A.
Noone will ever bother to check if its true. Boom. EU MEMBERSHIP GRANTED.
failing that come stay here for a few days and I’ll tell them you annexed my garage. Sorted.
I think you need to annex HIS garage, such that it becomes EU territory.
Are you threatening to annex my garage Wes… This wont go unpunished 
Unfortunately I suspect not. Well, maybe there will be a 64bit executable bundled in too, but there are an awful lot of casual gamers who are running 32bit versions of Windows that MS won’t want to exclude. They will be aiming for the widest consumer base possible, so I expect it to be tailored more to the above market segment rather than for us hard-core simmers.
Or maybe I’m wrong 
In reality is at least four years that software companies (both gaming and non-gaming) are progressively dropping 32-bit support.
Nvidia itself stopped caring for the lesser last year.
Beside some peculiar cases, real-world users (not just gamers) have all but left 32-bit OS behind; the numbers are abysmally low.
We have 32bit Windows 7 at the office, but we’re slowly replacing workstations with 64bit Windows 10 desktops or laptops for the sales guys.
Xbox One is also 64bit. So there is no real reason to support 32bit.
There were quite a few low end laptops etc here in the UK which came pre-installed with 32bit Windows Home, for instance. Many of these were sold over the last few years.
Allow me to believe that in the grand scheme of things it’s highly unlikely MS will target those to sell their new and graphically mouthwatering flight sim…
EDIT: I’m mostly talking about this…
We can but keep our fingers crossed 
2020 and 32-bit game running on new tech? I highly doubt that. Even MS with Azure AI wouldn’t woked out that magic. FSX was struggling with 32-bit. Remember you can’t address more than 4GB RAM (system + video) with 32-bit.
Actually 16-bit support was dumped for 64-bit OS-es. That’s why there’s so much trouble installing older games/apps which could still be run as they are 32-bit, but their installers are 16-bit and wont work.
And add to that, DCS is 64bit with 32bit having been dropped.
Ok, I seem to have derailed this discussion by not really making myself clear.
Of course I don’t have a 32bit OS for simming.
Of course anyone with any sense who bought a system with simming in mind wouldn’t have bought a 32bit OS.
Of course 32bit apps run fine on 64bit.
Of course there aren’t any 32bit OS systems on the market now. But there were just a couple of years ago.
My point was that MS will want to aim for the widest possible market - the MSFS franchise were generally well suited to inexperienced gamers. This market potentially includes people who don’t know what they’re doing when choosing a system. It includes those parents who buy their teenage children budget laptops thinking they got a great deal, and didn’t understand the limitations of the OS. And if the game streams the graphics, offloading all the difficult computation to the servers, the a 32bit client may well be sufficient.
I had someone in mind when writing that original post who did exactly this less than two years ago.
And as I also said in that post, I may be wrong.
The streaming point could be very valid - hopefully those same people aren’t also doing such budget minded deals on their internet connections. Although, with Netflix now so popular I’d gather most have something at least sufficient.
At least we don’t have to worry about 128 bit OS’s anytime soon!
